JMDM-12DIO8AIO serial port control of the analog digital input and output control syetem, is a high-reliable stability

industrial-grade SCM control system which independent research and development by Shenzhen jingmin digital machine

Co.,Ltd. with the main feature of analog control, can also be called as JMDM-12DIO8AIO online momitoring communication

system, JMDM-RS485/232 serial port control analog system. Realized using the Computer serial port line monitoring of

the digital and analog input status; real-time control of the analog and digital output,support through RS232 serial port

to extension of I/O points, A/D and D/A points, can be used for the computer serial port to achieve the control of analog

and digital signal,experiment and a variety of industrial application .

2. Technical parameters and functions of JMDM-10DIO10AIO

output has overvoltage protection circuit, anti-lightning and static shock;

2) working power: AC 18V or DC 24V, having overvoltage protection and lightning static protection function.

3) Using the latest high-speed C8051 Series SCM.

4) Program memory space is 64K and data storage space is 32K.(use perfect ferroelectric memory technology);

5)Digital input and output section,analog section:

Full-optically isolated digital (I / O) section:

4-channel input: the input voltage is 12V~24V, the input current is 10MA,NPN type(Active-low);

6-channel output: the output voltage is 12V~24V, output current is 4A, NPN type;

(12 bit ) high-precision high-speed analog parts:

8-channel input: 0~10V voltage input, can customized for 0~5V voltage input format or 0~20MA current input format; having

overvoltage protection and lightning static protection function.

2-channel ouput: 0~10V voltage ouput, the ouput current is 20MA, can also be customized for 0~5V voltage output; having

overvoltage protection and lightning static protection function.

6) RS232 interface: 2-channel standard RS232 serial port communication interface, having the following merit:

Can support to communicate with two peripheral device or host controller (computer or PLC)at the same time.

support the function extension of I/O, A/D, D/A, Facilitate a variety of multi-channel digital and analog control

requirements;

7) circuit board production use of SMD soldering, stable and reliable.

8) simple needs with RS232 communication, Is a one-to-one relationship between the computer and the controller, the

communication distance up to 10 meters;

9) Complex needs can use RS485 communication, between the computer and the controller is one to many relationship; the

communication distance can up to about 1 km, each controller can be set to a different address,a computer or master PLC

can up to control 255 controller.

3. Applications:

1) Serial port conmmunication automation devices;

2) automated quality detector:

3) product line intelligence detector:

4) the collection control of a variety of analog signal, such as the acquisition and control of pressure, temperature,

current, humidity, voltage signal.

5) The output control of the analog signal, such as proportional valve control, analog control the invertor, etc.
